The Ideal All-In-One Water Cooler: Separating the Stallions from the Donkeys

The best AIO water cooler won’t jump out at you at soon you start your shop. If you pay attention to the information below, however, you’ll have an easier time separating the best water coolers from the ones that won’t cut it for your CPU.

  • Case Compatibility. Every computer tower has a case that’s built specifically for the equipment and hardware inside of it, and the AIO water cooler you’re looking to purchase has to adhere to your computer case’s parameters.

Typical-sized water coolers will be compatible with most computer cases while bigger ones, such as those that are thicker than 240mm, will have to mounted differently.

Ultimately, you’ll have to take into consideration the amount of fan openings your computer case has on it. For the most part, each fan opening’s surface area is 120mm.

  • Radiator Fan Thickness. Higher-end models of AIO water coolers feature two fans, which may not be compatible with openings of your tower case. You can circumvent this issue by purchasing an AIO water cooler with a fan that’s slightly thicker, which will offer better performance than a single fan system normally would.

Fan thicknesses start at a base of 25mm and can be as thick as 49mm.

  • Noise. You might opt for an AIO water cooler with supplemental fans, but we warned! More fans usually equal more noise.
  • Targeted Area. While most All-In-One cooling systems primarily cool your CPU, some are also designed to cool your GPU, which has as much, if not more potential to overheat than your CPU. Keep in mind the areas of your build that you want to have cooled before you make a final purchase.
